I have to install an application that relies on a web server (XAMPP), so I'd like to add to my setup wizard a form that notifies the user if a given folder (of XAMPP) does not exist, then to provide a textbox and to ask the user to specify a folder name where this web server is installed.
I'd like to keep this folder name as a variable, since later I have to place some files in that folder.
Can you guide me how to do so?
Thank you
